This application claims the benefit of U.S. Provisional Application Ser. No. 60/570,326 filed May 12, 2004, the disclosure of which is incorporated herein by reference thereto.

FIELD OF THE INVENTION

The present invention relates to novel CXCR1 and CXCR2 chemokine antagonists, pharmaceutical compositions containing the compounds and methods of treatment using the compounds, compositions and formulations to treat CXCR1 and/or CXCR2 chemokine-mediated diseases such as acute and chronic inflammatory disorders, psoriasis, stroke, multiple sclerosis and cancer.

BACKGROUND OF THE INVENTION

Chemokines are chemotactic cytokines that are released by a wide variety of cells to attract macrophages, T-cells, eosinophils, basophils, neutrophils and endothelial cells to sites of inflammation and tumor growth. There are two main classes of chemokines, the CXC-chemokines and the CC-chemokines. The class depends on whether the first two cysteines are separated by a single amino acid (CXC-chemokines) or are adjacent (CC-chemokines). The CXC-chemokines include, but are not limited to, interleukin-8 (IL-8), neutrophil-activating protein-1 (NAP-1), neutrophil-activating protein-2 (NAP-2), GROα, GROβ, GROγ, ENA-78, GCP-2, IP-10, MIG and PF4. CC chemokines include, but are not limited to, RANTES, MIP-1α, MIP-2β, monocyte chemotactic protein-1 (MCP-1), MCP-2, MCP-3, CCL19, CCL21 and eotaxin. Individual members of the chemokine families are known to be bound by at least one chemokine receptor, with CXC-chemokines generally bound by members of the CXCR class of receptors, and CC-chemokines by members of the CCR class of receptors. For example, IL-8 is bound by the CXCR-1 and CXCR-2 receptors.

Since CXC-chemokines promote the accumulation and activation of neutrophils, these chemokines have been implicated in a wide range of acute and chronic inflammatory disorders including psoriasis and rheumatoid arthritis. Baggiolini et al., FEBS Lett. 307, 97 (1992); Miller et al., Crit. Rev. Immunol. 12, 17 (1992); Oppenheim et al., Annu. Fev. Immunol. 9, 617 (1991); Seitz et al., J. Clin. Invest. 87, 463 (1991); Miller et al., Am. Rev. Respir. Dis. 146, 427 (1992); Donnely et al., Lancet 341, 643 (1993).

ELRCXC chemokines including IL-8, GROα, GROβ, GROγ, NAP-2, and ENA-78 (Strieter et al. 1995 JBC 270 p. 27348-57) have also been implicated in the induction of tumor angiogenesis (new blood vessel growth). All of these chemokines are believed to exert their actions by binding to the 7 transmembrane G-protein coupled receptor CXCR2 (also known as IL-8RB), while IL-8 also binds CXCR1 (also known as IL-8RA). Thus, their angiogenic activity is due to their binding to and activation of CXCR2, and possible CXCR1 for IL-8, expressed on the surface of vascular endothelial cells (ECs) in surrounding vessels.

Many different types of tumors have been shown to produce ELRCXC chemokines and their production has been correlated with a more aggressive phenotype (Inoue et al. 2000 Clin Cancer Res 6 p. 2104-2119) and poor prognosis (Yoneda et. al. 1998 J Nat Cancer Inst 90 p. 447-454). Chemokines are potent chemotactic factors and the ELRCXC chemokines have been shown to induce EC chemotaxis. Thus, these chemokines probably induce chemotaxis of endothelial cells toward their site of production in the tumor. This may be a critical step in the induction of angiogenesis by the tumor. Inhibitors of CXCR2 or dual inhibitors of CXCR2 and CXCR1 will inhibit the angiogenic activity of the ELRCXC chemokines and therefore block the growth of the tumor. This anti-tumor activity has been demonstrated for antibodies to IL-8 (Arenberg et al. 1996 J Clin Invest 97 p. 2792-2802), ENA-78 (Arenberg et al. 1998 J Clin Invest 102 p. 465-72), and GROα (Haghnegahdar et al. J. Leukoc Biology 2000 67 p. 53-62).

Many tumor cells have also been shown to express CXCR2 and thus tumor cells may also stimulate their own growth when they secrete ELRCXC chemokines. Thus, along with decreasing angiogenesis, inhibitors of CXCR2 may directly inhibit the growth of tumor cells.

Hence, the CXC-chemokine receptors represent promising targets for the development of novel anti-inflammatory and anti-tumor agents.

There remains a need for compounds that are capable of modulating activity at CXC-chemokine receptors. For example, conditions associated with an increase in IL-8 production (which is responsible for chemotaxis of neutrophil and T-cell subsets into the inflammatory site and growth of tumors) would benefit by compounds that are inhibitors of IL-8 receptor binding.

For preparing pharmaceutical compositions from the compounds described by this invention, inert, pharmaceutically acceptable carriers can be either solid or liquid. Solid form preparations include powders, tablets, dispersible granules, capsules, cachets and suppositories. The powders and tablets may be comprised of from about 5 to about 95 percent active ingredient. Suitable solid carriers are known in the art, e.g., magnesium carbonate, magnesium stearate, talc, sugar or lactose. Tablets, powders, cachets and capsules can be used as solid dosage forms suitable for oral administration. Examples of pharmaceutically acceptable carriers and methods of manufacture for various compositions may be found in A. Gennaro (ed.), Remington: The Science and Practice of Pharmacy, 20^(th) Edition, (2000), Lippincott Williams & Wilkins, Baltimore, Md. which is incorporated herein by reference.

Liquid form preparations include solutions, suspensions and emulsions. As an example may be mentioned water or water-propylene glycol solutions for parenteral injection or addition of sweeteners and opacifiers for oral solutions, suspensions and emulsions. Liquid form preparations may also include solutions for intranasal administration.

Aerosol preparations suitable for inhalation may include solutions and solids in powder form, which may be in combination with a pharmaceutically acceptable carrier, such as an inert compressed gas, e.g. nitrogen.

Also included are solid form preparations which are intended to be converted, shortly before use, to liquid form preparations for either oral or parenteral administration. Such liquid forms include solutions, suspensions and emulsions.

The compounds of the invention may also be deliverable transdermally. The transdermal composition can take the form of creams, lotions, aerosols and/or emulsions and can be included in a transdermal patch of the matrix or reservoir type as are conventional in the art for this purpose.

The compound can be administered orally.

A suitable pharmaceutical preparation is in a unit dosage form. In such form, the preparation is subdivided into suitably sized unit doses containing appropriate quantities of the active component, e.g., an effective amount to achieve the desired purpose.

The quantity of active compound in a unit dose of preparation may be varied or adjusted from about 0.01 mg to about 1000 mg, or from about 0.01 mg to about 750 mg, or from about 0.01 mg to about 500 mg, or from about 0.01 mg to about 250 mg, according to the particular application.

The actual dosage employed may be varied depending upon the requirements of the patient and the severity of the condition being treated. Determination of the proper dosage regimen for a particular situation is within the skill of the art. For convenience, the total dosage may be divided and administered in portions during the day as required.

The amount and frequency of administration of the compounds of the invention and/or the pharmaceutically acceptable salts thereof will be regulated according to the judgment of the attending clinician considering such factors as age, condition and size of the patient as well as severity of the symptoms being treated. A typical recommended daily dosage regimen for oral administration can range from about 0.04 mg/day to about 4000 mg/day, in two to four divided doses.

Methods for the safe and effective administration of the above-mentioned microtubule affecting agents are known to those skilled in the art. In addition, their administration is described in the standard literature. For example, the administration of many of the chemotherapeutic agents is described in the “Physicians' Desk Reference” (PDR), e.g., 2003 edition (Thompson P D R, Montvale, N.J. 07645-1742, USA); the disclosure of which is incorporated herein by reference thereto.

The amount and frequency of administration of the compounds of formula (1) and the chemotherapeutic agents and/or radiation therapy will be regulated according to the judgment of the attending clinician (physician) considering such factors as age, condition and size of the patient as well as severity of the disease being treated. A dosage regimen of the compound of formula (1) can be oral administration of from 10 mg to 2000 mg/day, or 10 to 1000 mg/day, or 50 to 600 mg/day, in two to four (or two) divided doses, to block tumor growth. Intermittent therapy (e.g., one week out of three weeks or three out of four weeks) may also be used.

The chemotherapeutic agent and/or radiation therapy can be administered according to therapeutic protocols well known in the art. It will be apparent to those skilled in the art that the administration of the chemotherapeutic agent and/or radiation therapy can be varied depending on the disease being treated and the known effects of the chemotherapeutic agent and/or radiation therapy on that disease. Also, in accordance with the knowledge of the skilled clinician, the therapeutic protocols (e.g., dosage amounts and times of administration) can be varied in view of the observed effects of the administered therapeutic agents (i.e., antineoplastic agent or radiation) on the patient, and in view of the observed responses of the disease to the administered therapeutic agents.

If the compound of formula (1), and the chemotherapeutic agent and/or radiation are not administered simultaneously or essentially simultaneously, then the initial order of administration of the compound of formula (1), and the chemotherapeutic agent and/or radiation, may not be important. Thus, the compound of formula (1) may be administered first, followed by the administration of the chemotherapeutic agent and/or radiation; or the chemotherapeutic agent and/or radiation may be administered first, followed by the administration of the compound of formula (1). This alternate administration may be repeated during a single treatment protocol. The determination of the order of administration, and the number of repetitions of administration of each therapeutic agent during a treatment protocol, is well within the knowledge of the skilled physician after evaluation of the disease being treated and the condition of the patient.

For example, the chemotherapeutic agent and/or radiation may be administered first, especially if it is a cytotoxic agent, and then the treatment continued with the administration of the compound of formula (1) followed, where determined advantageous, by the administration of the chemotherapeutic agent and/or radiation, and so on until the treatment protocol is complete.

The particular choice of a compound of formula (1), and chemotherapeutic agent and/or radiation will depend upon the diagnosis of the attending physicians and their judgment of the condition of the patient and the appropriate treatment protocol.

Also, in general, the compound of formula (1) and the chemotherapeutic agent do not have to be administered in the same pharmaceutical composition, and may, because of different physical and chemical characteristics, have to be administered by different routes. For example, the compound of formula (1) may be administered orally to generate and maintain good blood levels thereof, while the chemotherapeutic agent may be administered intravenously. The determination of the mode of administration and the advisability of administration, where possible, in the same pharmaceutical composition, is well within the knowledge of the skilled clinician. The initial administration can be made according to established protocols known in the art, and then, based upon the observed effects, the dosage, modes of administration and times of administration can be modified by the skilled clinician.

Thus, in accordance with experience and knowledge, the practicing physician can modify each protocol for the administration of a component (therapeutic agent—i.e., the compound of formula (1), chemotherapeutic agent or radiation) of the treatment according to the individual patient's needs, as the treatment proceeds.

The attending clinician, in judging whether treatment is effective at the dosage administered, will consider the general well-being of the patient as well as more definite signs such as relief of disease-related symptoms, inhibition of tumor growth, actual shrinkage of the tumor, or inhibition of metastasis. Size of the tumor can be measured by standard methods such as radio-logical studies, e.g., CAT or MRI scan, and successive measurements can be used to judge whether or not growth of the tumor has been retarded or even reversed. Relief of disease-related symptoms such as pain, and improvement in overall condition can also be used to help judge effectiveness of treatment.

Compounds of formula (1) may be produced by processes known to those skilled in the art, in the following reaction schemes, and in the preparations and examples below.

PREPARATIVE EXAMPLE 1

Step A

To a stirred 300 mL CH₂Cl₂ solution in a −78° C. cooling bath was added chlorosulfonic acid (14.5 mL, 217.8 mmol). A solution of 3-methoxythiophene (10.0 g, 87.59 mmol) in 80 mL of CH₂Cl₂ was added slowly along the side wall of the flask. After 30 min, the cooling bath was removed. Reaction was continued at room temperature for 2 h. Stirring was stopped, the mixture was set still for approximately 10 min, and filtered directly and carefully through a 2-in silica gel pad. The green glue residue was extracted several times with CH₂Cl₂ and filtered. The filtrate was concentrated under reduced pressure to afford 10.75 g (58%) of thiophene-sulfonyl chloride as an off-white (trace green-grey) solid.

Step B

To a solution of thiophene-sulfonyl chloride (10.12 g, 47.58 mmol), obtained from step A, in 250 mL of CH₂Cl₂ at room temperature was added triethylamine (13.3 mL, 95.42 mmol) followed by diethyl amine (6.2 mL, 59.85 mmol). The mixture was stirred for 2 h, washed with H₂O (50 mL), a 1.0 M HCl aqueous solution (50 mL×2), H₂O (50 mL), and brine. The organic solution was dried with Na₂SO₄, and concentrated in vacuo to afford 11.54 g (97%) of diethylsulfonamide as a light wheat color solid (MH⁺=250.0).

Step C

To a stirred solution of diethylsulfonamide (11.54 g, 46.28 mmol), available from step B above, in 230 mL of CH₂Cl₂ at −78° C. was added dropwise along the sidewall of the flask a 1.0 M solution of boron tribromide in CH₂Cl₂ (58 mL, 58.0 mmol) The resulting mixture was stirred over night while temperature of the cooling bath was increased slowly from −78° C. to 10° C. H₂O (150 mL) was added. The mixture was separated. The aqueous layer was extracted with CH₂CO₂ (150 mL); and the combined organic layers were washed with brine (100 mL), dried with Na₂SO₄, filtered, and concentrated in vacuo to give 11.16 g (crude, 100%) of the corresponding hydroxyl-thiophene as a dark brown oil (MH⁺=236.0).

Step D

Hydroxy-thiophene (11.16 g, ˜46.27 mmol), from step C above, was dissolved in 230 mL of CH₂Cl₂, and added with potassium carbonate (16.0 g, 116.0 mmol) at room temperature. Bromine (4.75 mL, 92.7 mmol) was added drop wise. After stirred for 18 h, the solution was decanted. The solid residue was extracted with CH₂Cl₂ (100 mL). The organic fractions were combined, washed with H₂O (100 mL×2) and a 10% Na₂S₂O₃ aqueous solution (100 mL×2). The Na₂S₂O₃ washings were acidified to pH ˜4 using a 1.0 M HCl aqueous solution, and extracted with CH₂Cl₂ (100 mL×2). All organic layers were combined, washed with brine, dried by Na₂SO₄, filtered, and concentrated in vacuo to yield 16.8 g (crude, 100%) of hydroxyl-thiophene bromide as a dark brown oil.

Step E

Hydroxyl-thiophene bromide (16.8 g, crude, ˜46.27 mmol), from step D above, was dissolved in 250 ml of acetone, and added with potassium carbonate (32.0 g, 232.0 mmol) followed by iodomethane (28 mL, 450 mmol). The resulting mixture was refluxed over night. After cooled to room temperature, 200 mL of CH₂Cl₂ was added, the mixture was filtered through a 1-in silica gel pad, rinsing with CH₂Cl₂. The filtrate was concentrated under reduced pressure to a dark brown oil, which was purified by flash column chromatography, eluting with hexanes, hexanes-CH₂Cl₂ (3:1, 2:1, v/v). Removal of solvents afforded 7.56 g (50%) of methoxy-thiophene bromide as a light yellow oil (M⁺=328, M+2=330).

Step F

An oven dried two-neck round bottom flask was equipped with a magnetic stirring bar, a condenser, a stopcock, and cooled under nitrogen. Solid palladium acetate, rac-BINAP, and cesium carbonate were added. The solid mixture was degassed via house vacuum, refilled with nitrogen. This process was repeated two more times. A solution of thiophene-bromide (5.5 g, 16.8 mmol, from step E) in 100 mL of toluene was added, followed by benzophenone imine. The mixture was stirred and heated at reflux for 3.5 d.
